Check Digit Verification of cas no

The CAS Registry Mumber 6903-83-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6903-83:
(6*6)+(5*9)+(4*0)+(3*3)+(2*8)+(1*3)=109
109 % 10 = 9
So 6903-83-9 is a valid CAS Registry Number.
